The core vulnerability stems directly from the t3lib_div::RemoveXSS method's failure to strip non-printable characters as evidenced by: 1) CVE description explicitly naming this API method 2) TYPO3 security bulletin stating 'specially crafted HTML injections via non printable characters' 3) Debian advisory linking CVE-2012-1608 to this method. This is the primary input sanitization function that would appear in stack traces when processing malicious payloads containing obfuscated XSS vectors.
